SETH J. YVAKELEY, OF NEV YORK, N. Y.

GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 362,685, dated May 10,1887.

(No model.)

To aZZ whom it may concern-.-

Be it known that I, SETH J. WAKELEY, of the city and county of New York,in the State of New York, have invented a new and useful Improvement inGas-Governors, of which the following is a specification.

My invention is applicable, generally, to governors for regulating thesupply of gas to a number of burners, but is particularly advantageouswhen employed for regulating gas of a comparatively high pressureas, forexample, from twenty-six to thirty inches, or thereabout, ofwater-pressure.

The invention relates to those gas-govern ors in which the valve hasconnected with it a float or drum immersed in a liquid contained withina suitable easing, the float or drum having its lower end open, so thatthe pressure of gas entering the float or drum, usually from theservice-pipe, may act upon the top thereof to close the valve more orless by reaction upon the liquid contained in the casing, and said floator drum being provided with wings or cup-shaped projections, which,being immersed in the liquid in the casing, re-

- tard the movement of the valve and prevent its too sudden operation.

Important objects of my invention are, as aforesaid, to provide agovernor which will act properly with gas under comparatively highpressure, and in which the valve will not be closed by any momentaryincrease in the pressure of gas.

The invention consists in novel combinations. of parts, which arehereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section of agovernor embodying my invention, the valve being shown open. Fig. 2 is ahorizontal section upon about the plane of the dotted line :0 m, Fig. 1;and Fig. 3 is a horizontal section of the valve upon about the plane ofthe dotted line y y, Fig. 1.

Similar letters of reference designate corre' sponding parts in theseveral figures.

A designates a valve-shell, having at one side apipe-socket, I), for aninletpipe, and at the other side a pipe-socket, b, for the outletpipe.YVithin this shell is a main valve-seat,

2), (here represented as conicah) and the shell be of metal ofanysuitable form, and which is adapted to contain mercury or otherliquid, B. The casing A is, as here shown, screwed into the valve-shellA, and has a downwardly-projecting plug, A", (here shown as conicah) andwhich forms a supplemental or second valveseat, as I shall now describe.

The valve 0 here shown is a hollow conical valve open at both ends, andwhich by a rising movement closes its exterior upon the seat b and itsinterior at the upper end upon the plug A which forms the secondvalve-seat; hence it will be seen that by a slight downward movement anopening for the passage of gas will be afforded between the seat If andthe exterior of the valve 0 and between the seat A and the interior ofsaid valve.

\Vith the valve is connecteda drum or float, D, which is closed at theupper end and open at the lower end, and which isimmersedin the mercuryor other liquid, B, contained in the casing A. This drum B is connectedwith the valve 0, so that a risingmovement of the drum will close thevalve. The stem which connects the drum D and the valve 0 is, as hereshown, composed of anumberof rods or wires, 0, which are arrangedexternal to or around the plug A forming the second va1ve-scat,and'

which are preferably so connected with the valve 0 above the portionbearing on the seat I)" as to provide for. the self-adjustment of thevalve relatively to its seats. As here represented, a wire, 0, surroundsthe valve below a shoulder, c", thereon, and the lower ends of the wires0 are hooked, as shown at c, to engage said wire. I have here shown twowires or rods, 0, as composing the valve-stem; butit is obvious that agreater number might be used. A. flexible connection or attachmentbetween the rods or wires 0 and the valve 0 is important, because suchflexible connection or attachment provides for the free self-adjust mentof the valve to its seats, audit is advantageous to have the rods orwires 0 connected with an annular wire or band, 0, surrounding thevalve, because, then, by simply removing the bonnet or cap A, closingthe lower end of the valve-shell A, the valve 0 may be turned to grindit upon its seats without disconnecting it from any of the partsemployed in connection with it. I have here represented the plug A,which forms the second or supplegas from them into the drum D, even ifthe drum be lowered so that it rests upon the top of the tubes.

It will be observed that the drum D communicates with the delivery sideof the valve, or with the service-pipe which extends from the socket b,and hence said drum will always contain the same pressure which is inthe service-pipes,' and any sudden increase of pressure cannotimmediately shut off-the gas, be-

cause the service-pipes are supplied from the drum.

It will be understood that gas is intended to flow through the valve 0,in this example of my invention,-in the direction of the arrows shown inFig. 1.

In governors of this character it is important to prevent any suddenincrease in the pressure of gas from acting too quickly to raise thedrum D, and thus entirely shut off the supply of gas to theservice-pipes. I retard the movement of the drum, which will be producedby an increased pressure of gas, by providing the drum D upon itsoutside with wings, fins, or projecting blades, which are immersed inthe mercury or other liquid, B, contained in the casing A, and whichconsists of a series of cups which are presented upward and are formedupon or attached to the drumD. These cups present a large surface to theliquid within the casing A, and any upward movement of the drum will beretarded or controlled by the weight of the liquid until the liquidraised by the cups can have an opportunity of flowing downward around orthrough them. In the bottom of the cupshaped wings f are perforations f,through which the mercury or otherliquid, B, may pass slowly downward,and by such arrangement the upward movement of the drum D, due to asudden increase in the pressure of gas, is materially retarded, so thatthe drum and its attached valve can move upward but very slowly, and theclosing of the valve will be slow.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a valve-shell containing two concentricvalve-seats and a gasvalve substantially balanced and closing on saidseats, of a gas-receiving drum connected with the valve and constructedwith outwardly -projectin'g wings and a casing within which the drum isarranged for containingliquid to immerse the wings on the drum,substantially as and for the'purpose herein described.

2. The combination, with a valveshell and gas-valve, of a gas-receivingdrum connected with the valve-stem and having outwardlyprojecting cupshaped wings f, perforated at f, and a casing within which the drum isarranged for containing liquid to immerse the wings of the drum,substantially as herein described.

3. The combination, with a valve-shell and gas-valve and a gas-receivingdrum to be immersed in liquid, of a stem connecting the drum and valveand composed of two or more wires or rods having at theirlower ends aloose or flexible attachment to the valve at its periphery, to providefor its selfadjustment to its seat, substantial] y as herein described.

4. The combination, with the shell A, having the seat I), and thesurmounting casing A, having the downwardly-projecting plug A forming asecond seat, of the valve 0, closing on both seats, the drum D, a stemconnecting the valve and drum and composed of a number of wires or rods,0, around the upper valveseat, and the tubes 6, rising from the bottomof the casing and surrounding the wires or rods, substantially as hereindescribed.

5. The combination, with the valve shell A,

of the valve 0, having asurrounding band, 0,

and wires or rods hooked onto said band and forming a valve-stem,substantially as herein described.
